I-15 & 900 South Delivery Method
• Why PDB for this Project?• Department did not know the scope.• Needed Contractors ability/help to adequately evaluate the situation.• Arrive at a collaborative and optimized solution. • Delivery method best fit the situation
UDOT’s Approach to Progressive Design-Build1) Qualification Based Selection: Looked to partner with the
Contractor to develop the PDB process.
2) Scope Evaluation: Ability to make better informed decisions with the Contractor assisting.
3) Open Book Price Evaluation: Construction pricing used two Independent Cost Estimate (ICE) for bid reconciliation.
4) Contract Structure: Final contract structure is based on UDOT’s Design-Build template.
UDOT’s PDB Workflow
Mind Shift to PDB from DB or CMGC• Alternate Technical Concepts (ATC) => Progressive Concept Evaluation (PCE)• Request For Proposal (RFP) => Basis for Design & Construction (BDC)• Opinion of Probably Construction Cost (OPCC) => Construction Price and
Proposal (CPP)
Getting the Project UDOT Wants1) Opportunity: An Owner-controlled, Contractor-involved
scoping
2) Optimization: Constructability and innovation integrated into the project
3) Reliable: Collaborative risk allocation to resolve project challenges – use of provisional sums.
A Community-Influenced Project
Accelerated Delivery: DB vs. PDB
Schedule Savings:8 months
$489M
A Different Team Structure
1) Contractor-engaged input during scoping phase
2) A collaborative Owner-Contractor relationship
3) Program Manager as an extension of UDOT staff
4) ICE to validate pricing

A Focus on Optimization
All team members developed progressive concepts to:
1) Enhance constructability from day 1
2) Challenge preferences and expand new techniques
3) Engage challenges and constraints head on
BEFORE
Optimizing Oak Hills Road
New culvert
Stringent BOR requirements over its
waterline
Limited access to the Holmes Creek area
US Forest Trailhead
Access
Major petroleum supply line
Created location for project fill (94K CY):
$600k savings
Improved access to the Holmes Creek
area
Eliminated need for box culvert:
$500k savings
Mitigated BOR impacts w/ lightweight fill and wall:
$1.2M savings
Savings Total:$2.3M
Combined trailhead parking and transit park-n-ride facility
AFTER
A Quality Organizational Structure that Improved Efficiency
Construction Proposal and Pricing (CPP)• Utah Law Requires 3 Estimates• Project Goal +/- 5%, Actual was < 2.0%
US-89 Progress• Contractor Selected Fall 2018• Contractor Mobilized Equipment Spring 2019 for limited work.• Currently the site evaluation is complete and design is 75% complete• NTP and ATP1 was Jan 2020• ATP 2 was Feb 2020
I-15 & 900 South Progress• Contractor Selected Summer 2019• Contractor Mobilized Equipment Fall 2019• Currently the site evaluation is complete and design is complete• Price is being negotiated in anticipation of work in summer 2020
Lessons Learned:
• Project was way under budget and being sued; which caused unknown schedule duration – PDB was chosen because of this
• Blended roles of the Design-Builder
• Established budget and schedule expectations
• Engagement of the program management team simultaneously
• Right-size independent estimating resources
• Risk allocation is more dynamic due to conforming nature of the contract
Lessons Learned: PDB Value Added
• Innovation and creativity due to loosely defined scope
• Release of early packages
• Risk reduction through focused geotechnical investigations
• Feasible MOT plan that reduced local and highway impacts
• Construction Quality Management Plan approved prior to Contract – This allowed the Contractor to accurately bid the project with little risk.
• Utilization of existing materials
Lessons Learned: PDB Value Added
• Unconstrained dialogue to explore innovative concepts
• Public Trust
• No Surprises
• Contractually
• Publicly
• Contractor is involved in Contract Creation (Not a lowest common denominator contract)
